UNITED STATES PATENT OFFICE.

HENRY RUPPEL, OF CLEVELAND, OHIO, ASSIGNOR TO THE DANGLER STOVE ANDMANUFACTURING COMPANY.

VAPOR-STOVE.

SPECIFICATION forming part of Letters Patent No. 480,281, dated August9, 1892.

Application filed September 23, 1891. Serial No. 406,592. (No model.)

To all whom it may concern:

Be it known that I, HENRY RUPPEL, a citizen of the United States,residing at Cleveland, in the county of Ouyahog'a and State of Ohio,have invented a certain new and Improved Vapor-Stove, of which thefollowing is a full, clear, and complete description.

The nature of my invention relates to the burners and generating deviceof the stove and to the valves in connection with the tank, also to theform of the tank, as hereinafter fully described.

That the invention may be seen and fully understood by others referencewill be had to the following specification and annexed drawings, formingpart thereof.

Figure 1 is a vertical longitudinal section of my improved burner andgenerator. Fig. 2 is an end View of the tank and connectingvalve. Fig. 3is a reduced side view of the tank. Fig. 4 is a cross-section on dottedline 00 as, Fig. 1. Fig. 5 is an end view of the stove without the ovenand oven-burner. Fig. 6 is a View of one of the burners with a portionof one of the tubes broken away. Fig. 7 is a cross-section on line .2 z,Fig. 6; and Fig. 8 is a View of the under side of the burner.

Similar letters designate similar parts in the drawings andspecification.

As shown in Figs. 1 and 6, the burner is constructed with a cylinder A,having a cover B, sawed as shown at a a a, Figs. 1 and 4. A tube 0extends down through the center of the cylinder A and terminates at thelower end in a square chamber 17, one side of which is sawed, as shownin Fig. 1. In contact with this chamber on the opposite side from thesawed portion is a tube 0, in open connection with the generating-tubeD. The lower terminal of the cylinder A is closed, except in the center,which is left in open connection with the chamber 1) and tube 0, thecross-piece It simply spanning the opening to hold the screw Z. Thebottom at of the cylinder A is of one piece pressed or struck up, asshown, and connected with the main portion of the cylinder, as shown ate, Fig. 1. By this construction any overflow of gasoline that may be isretained within the cylinder, all leakage being prevented. A drum Ecircumscribes the cylinder A, allowing an annular chamber f entirelyaround the upper portion of the cylinder. This annular chamber is openat the bottom and closed at the top, as shown,

and is in open connection with a rectangular flat tube or conductor F.The conductor F is in open connection with an annular chamber G,surrounding the generating-tube D. Thus the hot air is carried from theburner through the fiat tube or conductor F to the annular chamber G,surrounding the generating-tube, and materially aiding in thevaporization. The gasoline is not allowed to run from the tank into theburner, the valves H, Figs. 2, 3, and 5, being so adjusted as to permitthe gasoline to drip on the cap of the perforated thimble g, Fig. 1.This, aided by the hot air from the burner, causes the generation of thevapor. It will be noted that the chamber G completely incloses the upperportion of the generating-tube, thus causing a uniform circulation ofheat around the tube. The heavy gasoline not vaporized passes down thetube and is vaporized in the tube 0 by the intense heat impinged thereonthrough the slots in the chamber 1).

The valves used in connection with my improved vapor-stove aresubstantially of the form shown in Fig. 2, having a stop h arrangedthereon for the purpose of adjusting the flow of gasoline. They are alsoprovided with an opening 1' for the purpose of cleaning the valve. Thereis an individual valve for each burner, as shown in Fig. 3. There-' foreif one valve is out of order the utility of the others is not affected.This also gives a direct pressure from the tank for each burner. Thetank, being long and shallow, gives an even drip to the gasoline whenthe tank is full and when partially full. The cap I, covering the upperpart of the hot-air chamber G and in which the stem of the valve rests,is removable, as shown in Fig. 1. A ing 0 is cast on the cap. This lugpasses through a hole in the casing of the chamber below the bead p. Aspring-latch r laps over the bead on the opposite side.

What I claim, and desire to secure by Letters Patent, is

A vapor-burner composed of a cylinder havinga sawed cap thereon, withahole in the In testimony whereof Iaffix mysignatnre in center thereof,and a tube 0, in open relation presence of two Witnesses. to said holeand passing down through the center of said cylinder, in conjointoperation HENRY RUPPEL. 5 With a rectangular sawed chamber 1) and tubec, in combination with the generating-tube Witnesses:
